Another important obj ect of my invention isthe-p'rovision of the combination middle'and inner `sole fori receiving theupper end ofthe cushioning pad so as to permit the niaxin'ium aniountlof` beneiitto be obtained: from the AVcushioning pad with` a minimum amount. of material between the pad and the heelof the wearer.

Anothersalient object of" my invention is the provision-.of a resilientf'heel piece adapted to bepermanently :placed betu'reen'the combination middle andinner sole and outer soleof a shoe, the resilient heel lpiece carrying-fa cushioning padrso disposed and arranged as to form ineffective cushioning support for he calcaneumfbone ofy a foot of-the wearer of the shoe.` ,A still further object of "my invention: is to provide a cushion heel support or kpocket for the calcaneum bone to restinWhen :walk ingpof the above character,` whichwill be durable and kefficient in use, one that will be simple Vand easy'fto manufacture, and one be incorporated with a conventional shoe ata low cost. r

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described,

, One-ofthe-'salient features of my invention isthe provision of the ycushion heel piecel which is shaped to conform to the construction or configuration ofV the heel -portions of the combination middle and inner sole 10 and outer sole 11 and the bodyk portion of the cushion heel piece 15 can be Ythe combination middleandV in.

that the pad in this modified form also eX- ten'dsmaterially above and below" the opposite faces of the .heel piece 15 and while I have specified that the combination middle v and -inner sole and `theouter sole are `cemented together, it is to be understood that the same canbe also sewed together."v

will effectually prevent what istermed by orthopedists as oscillating or rotating heel bones which the direct'cause of distorted heel seats in spring heel shoes for children and; crooked heels on shoes worn by adults, this .being accomplished by reason of the fact that a liexible cushion is provided whichwill tend to effectively hold the heel bones in proper anchored position, the heel bonesnot having a tendency to slip or rotate 4within the `heel. of Vthe shoe.
